They not only commit source code but also exert significant efforts on other communicative, organizational, and supportive activities. However, almost all prior research focuses on specific activities and fails to analyze elite developers\u2019 activities in a comprehensive way. To bridge this gap, we conduct an empirical study with fine-grained event data from 20 large open source projects hosted on G\n IT<\/jats:sc>\n H\n UB<\/jats:sc>\n . We investigate elite developers\u2019 contributing activities and their impacts on project outcomes. Our analyses reveal three key findings: (1) elite developers participate in a variety of activities, of which technical contributions (e.g., coding) only account for a small proportion; (2) as the project grows, elite developers tend to put more effort into supportive and communicative activities and less effort into coding; and (3) elite developers\u2019 efforts in nontechnical activities are negatively correlated with the project\u2019s outcomes in terms of productivity and quality in general, except for a positive correlation with the bug fix rate (a quality indicator). These results provide an integrated view of elite developers\u2019 activities and can inform an individual\u2019s decision making about effort allocation, which could lead to improved project outcomes. The results also provide implications for supporting these elite developers.\n <\/jats:p>","DOI":"10.1145\/3387111","type":"journal-article","created":{"date-parts":[[2020,6,1]],"date-time":"2020-06-01T16:19:41Z","timestamp":1591028381000},"page":"1-35","update-policy":"http:\/\/dx.doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":19,"title":["Unveiling Elite Developers\u2019 Activities in Open Source Projects"],"prefix":"10.1145","volume":"29","author":[{"given":"Zhendong","family":"Wang","sequence":"first","affiliation":[{"name":"University of California, Irvine, California"}]},{"given":"Yang","family":"Feng","sequence":"additional","affiliation":[{"name":"Nanjing University, Jiangsu, China"}]},{"given":"Yi","family":"Wang","sequence":"additional","affiliation":[{"name":"Rochester Institute of Technology, New York"}]},{"given":"James A.","family":"Jones","sequence":"additional","affiliation":[{"name":"University of California, Irvine, California"}]},{"given":"David","family":"Redmiles","sequence":"additional","affiliation":[{"name":"University of California, Irvine, California"}]}],"member":"320","published-online":{"date-parts":[[2020,6]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1109\/MS.2007.2"},{"key":"e_1_2_1_2_1","volume-title":"Proceedings of the 2006 International Workshop on Economics Driven Software Engineering Research (EDSER\u201906)","author":"Amor Juan Jose"},{"key":"e_1_2_1_3_1","volume-title":"Proceedings of the 28th International Conference on Software Engineering (ICSE\u201906)","author":"Anvik John"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.4324\/9781410600035"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10606-018-9310-8"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1145\/3236024.3236061"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.2307\/2118383"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1109\/ICSM.2011.6080832"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1145\/2025113.2025119"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1145\/1453101.1453107"},{"key":"e_1_2_1_11_1","volume-title":"Proceedings of the 2009 6th IEEE International Working Conference on Mining Software Repositories (MSR\u201909)","author":"Bird C.","year":"2009"},{"key":"e_1_2_1_12_1","doi-asserted-by":"publisher","DOI":"10.1109\/ISSRE.2013.6698918"},{"key":"e_1_2_1_13_1","volume-title":"Abbott","author":"Bordens Kenneth S.","year":"2002"},{"key":"e_1_2_1_14_1","volume-title":"Communication 8 Society 15","author":"Crawford Kate","year":"2012"},{"key":"e_1_2_1_15_1","doi-asserted-by":"publisher","DOI":"10.1177\/001316448104100307"},{"key":"e_1_2_1_16_1","volume-title":"Produktivit\u00e4t und Qualit\u00e4t in Software-Projekten: Psychologische Analyse und Optimierung von Arbeitsprozessen in der Software-Entwicklung, Felix C","author":"Brodbeck Felix C."},{"key":"e_1_2_1_17_1","doi-asserted-by":"publisher","DOI":"10.1145\/2393596.2393647"},{"key":"e_1_2_1_18_1","doi-asserted-by":"publisher","DOI":"10.1109\/TSE.2012.32"},{"key":"e_1_2_1_19_1","doi-asserted-by":"publisher","DOI":"10.1145\/3106237.3106285"},{"key":"e_1_2_1_20_1","volume-title":"Proceedings of the Thirty First International Conference on Information Systems (ICIS\u201910)","author":"Collier Benjamin"},{"key":"e_1_2_1_21_1","volume-title":"correlation, and big data in social science research.
